Configuration

ganglia_metrics
(boolean) Enable metrics using Ganglia. Note that enabling this option will have no effect if the service is not related to a ganglia service via the ganglia:master relation. Enabling this option with the relation will issue a restart to the NameNode and all DataNode components on all related compute-slaves. See the README for more information.
resources_mirror
(string) URL from which to fetch resources (e.g., Hadoop binaries) instead of Launchpad.
dfs_blocksize
(int) The default block size for new files (default to 64MB). Increase this in larger deployments for better large data set performance.
134217728
dfs_replication
(int) Default block replication. The actual number of replications can be specified when the file is created. The default is used if replication is not specified at file creation time.
